The Client programs, involving the PL/SQL programs, can declare the objects and collections, and pass them as parameters, store them in the database, recover them, and so on. Also, by encapsulating the operations with data, the object types move data-maintenance code out of the SQL scripts and PL/SQL blocks into methods.
The Objects and collections are well-organized to store and retrieve as they can be manipulated as an entire. The object support is also integrated architecturally with the database; therefore it can take benefit of the many scalability and performance improvements built into Oracle8i.
